Springfield Saint 5.56mm AR-15 Pistol with B5 Grip and Trinity Force Breach Blade Brace

Overview

The Springfield Saint 5.56mm AR-15 Pistol with B5 Grip and Trinity Force Breach Blade Brace represents a refined balance of compact maneuverability and deliberate engineering from Springfield Armory. Chambered in 5.56mm NATO, this pistol platform is constructed around a forged 7075 T6 aluminum upper and lower receiver set, paired with a 10.3-inch chrome moly vanadium barrel with a 1:7 twist rate. The inclusion of the B5 Systems pistol grip and the Trinity Force Breach Blade brace transforms the handling dynamics, offering a stable shooting interface without the length of a traditional rifle stock. This specific configuration, the Springfield Saint 5.56mm AR-15 Pistol with B5 Grip and Trinity Force Breach Blade Brace, is designed for users who require a short-barreled platform with enhanced control surfaces.

Features and Specs

Built on the proven Saint series architecture, this pistol utilizes a direct impingement gas system with a low-profile gas block and a free-floating M-Lok handguard. The barrel is finished with a Melonite treatment for corrosion resistance and extended service life. The B5 grip provides an improved ergonomic angle and a textured surface for positive hand purchase, while the Trinity Force Breach Blade brace uses a rigid polymer blade design that integrates with the buffer tube for single-point sling attachment capability. The pistol includes a standard mil-spec trigger group with a 5.5 to 6.5 pound pull weight and a nitride-coated bolt carrier group.
